    Abstract: A device with an I/O interface includes a replica clock distribution path matched to a clock distribution path of an unmatched receiver circuit. The device can monitor changes in delay in the replica path, and adjust delay in the real clock distribution path in response to the delay changes detected in the replica path. The receiver circuit includes a data path and a clock distribution network in an unmatched configuration. A ring oscillator circuit includes a replica clock distribution network matched to the real clock distribution network. Thus, delay changes detected for the replica clock distribution network indicates a change in delay in the real clock distribution network, which can be compensated accordingly.

    Abstract: Systems, apparatuses and methods may provide for determining a status of an enable signal and selecting a leaker resistance from a plurality of leaker resistances based at least in part on the status of the enable signal. Additionally, the selected leaker resistance may be applied to a data strobe line of a memory bus. In one example, the selected leaker resistance reduces ringback noise on the data strobe line.

    Abstract: I/O parameters are adjusted based on a number of errors detected in a received training signal. A controller device sends the training signal while a memory device is in a training mode. The memory device samples the training signal and the system causes an adjustment to at least one I/O parameter based on a detected number of errors. Either the controller or the memory device can perform the error detection, depending on the configuration of the system. Either an I/O parameter of the controller or an I/O parameter of the memory device can be adjusted, depending on the configuration of the system.

    Abstract: A memory subsystem includes a test engine coupled to a memory controller that can provide memory access transactions to the memory controller, bypassing a memory address decoder. The test engine receives a command to cause it to generate transactions to implement a memory test. The command identifies the test to implement, and the test engine generates one or more memory access transactions to implement the test on the memory device. The test engine passes the transactions to the memory controller, which can schedule the commands with its scheduler. Thus, the transactions cause deterministic behavior in the memory device because the transactions are executed as provided, while at the same time testing the actual operation of the device.
